Optics confidential

Optics Confidential is a blog with questions and answers on optical research, with emphasis in Visual, Ophthalmic and Biomedical Optics. The social impact of science and career development of young scientists is also covered.

The different optical components of the eye, the cornea and the crystalline lens are not properly aligned with the area of the retina (the fovea) providing the highest spatial resolution. Some information on this issue and a description of a new instrument to measure eye misalgnment is presented...... Read more »

A lecture describing in detail the optical properties of the eye given at the international Visual Optics School in Crete last summer. Useful to better understand the article in "Nature Photonics" ... Read more »

Aspheric intraocular lenses provide cataract patients with better quality of vision. The history of how these lenses were developed trying to copy the optical properties of young eyes is described ... Read more »

Why is this post inappropriate?

The visual system could be adapted to the particular optical properties of each person's eyes. An experiment using an adaptive optics visual simulator was used to demonstrate this hypothesis. Some details of the experiment and the impact of the finding are discussed...

Citations etiquette is a very important part of scientific research. Some comments on the topic and a practical example of one of my early papers where I first describe how to simulate retinal images of any object in real eyes for different conditions. The approach was widely used later but the paper poorly cited...... Read more »

A new type of light adjustable intraocular lenses promises patients to be spectacles-free after cataract surgery. See a description of these new lenses and how the optical results after sugery were controlled using a Hartmann-Shack wavefront sensor based refraction approach...... Read more »

The optics of the human eye impose the first limit to vision. We studied the eye's optics in a group of subjects having natural supervision, that is to say, excellent visual acuity. We discovered that having a superior visual acuity does not require an excellent optical quality of the eye...... Read more »

Some of the new advances in myopia research presented in a recent meeting is revised. In particular, I cover the differences in the optical properties of the myopic eye in the peripheral retina and the future potential optical approaches to control myopia development based in these findings....

The human eye suffers of a very large chromatic aberration. This means that when a red object is in focus, a blue one at the same distance will be clearly out of focus. Why we are not yet routinely correcting this defect to improve vision? You will find here some new experiments, results and explanations...... Read more »

Why is this post inappropriate?

A recently developed adaptive optics instrument for the two eyes is described. The way on how eventually this system may change the traditional and old fashioned way of testing vision and prescribing spectacles is discussed...... Read more »

Why is this post inappropriate?

Myopia is a refractive condition that eventually could be controlled by spectacles designed to change the optics in the periphery of the retina. Some of the new results on this exciting topic are described...... Read more »
